SUMMARY OF THE INVENTION

The present invention provides a method of creating a mashup application in a host device in communication with a peer device on the fly provided that both of the host device and the peer device comprise a mashup framework.

A peer device is identified and analyzed by a mashup framework in a mobile device.

After analyzing functions of a peer device service and the mobile device, the mashup framework suggests combinations of mashup applications that can be created in the peer device. The peer device selects a combination of mashup applications that needs be formed. According to the selected combination of mashup applications, each service shares data by using middleware allowing the peer device and the mobile device to share remote services.

Thereafter, the mashup framework creates a mashup code that can be executed in the peer device. The mashup code is a basic mashup functionality and can be executed provided that the mashup code has an intrinsic functionality of a host device. A peer-to-peer communication and middleware remote service shared between middleware frameworks of the mobile device and the peer device make it possible to communicate and share data between the mobile device and the peer device.

According to an aspect of the present invention, there is provided a method of creating a mashup application in a host device in communication with a peer device by sharing remote services, the method comprising: discovering a second device that uses a middleware remote service sharing mechanism within a network, wherein a mashup framework of a first device performs the discovering; analyzing functionalities of the first device and the second device, and determining one of them as a host device and another as the peer device; transmitting a list of available mashup combinations to the host device, wherein the peer device performs the transmitting; and selecting a mashup combination that is to be formed from the list, wherein the host device performs the selecting.

A mashup framework of the host device may create an executable mashup code having functionalities of the host device as basic functionalities used for the selected mashup combination.

After executing the mashup code, the mashup framework of the host device may notify a user via a mashup application that is dynamically created.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS OF THE INVENTION

Hereinafter, the present invention will be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

Exemplary embodiments of the invention are described herein with reference to illustrations that are schematic illustrations of idealized exemplary embodiments (and intermediate structures) of the invention. As such, variations from the form of the illustrations are to be expected. While describing the present invention, detailed descriptions about related well-known functions or configurations that may blur the points of the present invention are omitted.

According to the present invention, each device connected over a network comprises a mashup framework. A mashup framework of a first device uses a middleware remote service sharing mechanism or some general device discovery mechanisms to discover a second device over the network. The first and second devices analyze each other's functionalities and determine one of them as a host device and the other as a peer device. The peer device sends a list of available mashup combinations to the host device. The host device selects a mashup combination that is to be formed from the list. Also, a mashup framework of the host device creates an executable mashup code having functionalities of the host device as basic functionalities used for the selected mashup combination. After executing the mashup code, the mashup framework of the host device notifies a user that a mashup application has been dynamically created.

FIG. 1 is a block diagram of a mobile device 6 sharing middleware remote services and a peer device 11 involved in on the fly creation of a mashup from the mobile device 6 to the peer device 11 and elements thereof according to an exemplary embodiment of the present invention. Referring to FIG. 1, the mobile device 6 comprises a mashup framework 2, middleware 1, a virtual machine 5, device applications 4, a mashup application 3 and an operating system 0. The peer device 11 comprises a mashup framework 8, middleware 9, a virtual machine 12, device applications 10, a mashup application 7 and an operating system 0.

In the present exemplary embodiment, when both the mobile device 6 and the peer device 11 are located in the same subnet, both devices use a middleware remote service sharing mechanism or some general device discovery mechanisms to discover each other's mashup framework.

After discovering mashup services from the peer device 11, the mobile device 6, as a basic service, creates a list of combinations of mashup applications with regard to the peer device 11 having the functionality of the peer device 11.

After the mobile device 6 creates the list, the peer device 11 notifies a user of a mashup combination that can be created on the fly from the mobile device 6.

The peer device 11 returns confirmation of a necessary mashup combination to the mashup framework 8.

The middleware 1 of the mobile device 6 and the middleware 9 of the peer device 11 communicate with each other by sharing the middleware remote services in order to exchange services. A discovery of different middleware frameworks on the same subnet is managed by sharing the middleware remote services.

An executable code used for the selected mashup combination is created by the mashup framework 8 of the peer device 11, and is displayed on the peer device 11 together with information provided by a service of the mobile device 6 and information and services obtained from the peer device 11.

A navigation device 25 comprises a navigation mashup 23, a navigation mashup service 21, device application 22, a mashup framework 20, an OSGi 19 and a CDC/connected limited device configuration (CLDC) 24. The mobile device 18 and the navigation device 25 discover each other when both devices enter into the same subnet and exchange messages. The mashup frameworks 14 and 20 of respective devices 18 and 25 analyze each other's functionalities. According to the analyzed functionalities, the mashup frameworks 14 and 20 determine one of the devices 18 and 25 as a host device and transmit a list of available mashup combinations to the host device. The mashup framework of the host device creates an executable mashup code having the functionalities of the host device as a basic functionalities used for the selected mashup combination. After executing the mashup code, the mashup framework of the host device notifies a user via a mashup application that is to be dynamically created.

FIG. 3 is a flowchart of a method of creating a mashup application on the fly from a peer device by dynamically sharing remote services according to an exemplary embodiment of the present invention. Referring to FIG. 3, in operation 26, a mobile device and a peer device identify each other in a subnet. In operation 27, the mobile device analyzes the functionality of the peer device. After analyzing the functionality of the peer device, in operation 28, the mobile device sends a list of available mashup combinations to the peer device. In operation 29, the peer device notifies the mobile device of a selected mashup combination. According to the selected mashup combination, in operation 30, a mashup framework of the peer device creates an executable code in an appropriate script, and in operation 31, displays the executable code on the fly for a user.

According to the exemplary embodiments of the present invention, it is possible to create a device-to-device mashup application from a peer device to a host device.

The invention can also be embodied as computer readable codes on a computer readable recording medium.
